Lucid dreaming, where people experience waking-like self-reflection during dreams, is linked to more wake-like brain activity in the prefrontal cortex. This multi-centre study, combining four investigations, examined whether fragmented sleep increases the chance of lucid dreaming. Results showed that self-reported awakenings, polyphasic sleep schedules, and physiologically measured wake-REM sleep transitions were associated with lucid dreaming. However, neither self-assessed sleep quality nor physiologically measured numbers of awakenings showed an association. The findings suggest a nuanced relationship, where certain types of sleep fragmentation, but not all, may relate to lucid dreaming, and the authors discuss possible causal mechanisms.
